CLARK I.STOCKING, OF HIAWATHA, KANSAS.

l To all whom 'it 'may v concer-n:

` Hiawatha, in the county of Brown and State' of- Kansas, have inventedcertain new and- Beit known that I, CLARK I. Sinonimi, a citizen of theUnited States, residing at useful Improvements in Post- Brace Anchors';land I do declare the following to be,

A `a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertaiiis to make and usethesaine.

This invention relates to improvements inv post brace anchors. v

The object of the invention is provide a device of this characterwhichmay be readily 4engaged .with-the ground and operated to securely fastenitself in the earth thereby rigidly anchoring the post brace.

A further object is to provide a post brace anchor" having improvedconstruction f parts and means whereby they may be readily assembled foruse.

- arran ement of parts as will Abe more fully descri ed and particularlypointed out in the ap ended claim. f

In t e accompanying .drawin Figure 1 is a perspective view of the'devfie withthe parts in inoperative position Fig. 2-is averticalsectional view with the parts expanded in position for use; Fig.3 is a horizontal sectional view on the line 3-'3 of Fig. 1. l

Referring more particularly to the drawings, 1 denotes the anchor whichconsists of an expanding framehaving a substantially circular base, l2.The sides of the base are out away to provide diametrically oppositelugs, 3, from which project upwar -inwardly diverging arms, 4, which areconnectcd'together at their upper ends and in said upper ends is formeda vertically disposed assage which alines with asimilar passage in thecenter of the base plate. The arms, 4, have an lar, outer sides for apurpose hereinafter escribed and on thebottom of the base, 2, are formedV=shaped Vholding lugs which are adapted to engage the earth when -theexpander is in operative position', to

' e prevent the same from turning.

ut'er ends of the arms, 4, and in the base, 2,

l is an operating rod, 5, the inner end of which is provided with ahead,6, which enga es .the

lower side of the base, 2', and holds t e' ex- Loosely engaged with theapertures in the 'V\.\ EOST-BBACE ANCHO R.

pander iii aosition. 0n the outer end of the Patented lflebrSQQO.

-rod is pre erably formed an eye, 7. On the rod, 5, is a cross head, 8,said cross head havthe rod is revolved, said threaded lower end will bescrewed through the cross head. In

vthe opposite ends of the head are formed bearing apertures in the outer.portions of which are formed cylindrical bearin s, 9K

Operatively engaged with thehea 8, are anchoring wings, 10, each ofwhichconsists of arms, 19., having on their A upper ends hooks, 13, which areadapted to be engaged with the bearing apertures and bearings, 9, in theopposite ends of the: cross head, 8. On the lower ends of the arms' 12are formed laterally projecting segmental anchorn blades 14, which areadapted to be forcel into the earth in the manner hereinafter described.AIn the inner-side of the arms, 12 and inner edges of theblades, 14, areforme V-,shapedrooves, 15, which are adapted to be engage by thetriangular outer sides of the expandin frame, whereby when the saidexpander is rawnrupwardly by the opera- -tion of the rod, 5 inthethreaded 'aperture of the cross head the lower portion of said armsand blades will be expanded. On the outer sides of the arms, 12, areformed bracing webs, .16, in which adjacent to the blades, la.,l

blades to beexpanded. AWVheii the arms and blades are in a retractedposition, the inner edges of the blades 14 are broughttogether or intoclose relation and when the anchoring ai-iiis and blades are in anexpanded p07' sit-ion the base (5 of the expander will partly lill thespace between the expanded blades.

Iii the operation of the device a hole is first drilled iii the groundafter which the' anchor with its parts iii a retracted or inopcrativeposition is inserted intothe' drilled hole after which the voperatingrod' 1s .re-

volvcd in the proper direction to draw'the inner end of the.sametogether with the expander up between the anchoring arms and blades,thereby forcing the saine laterally into the earth, forming the sides ofthe bore.

Whenlthe anchoring blades have been thns expanded, the anchor will besecurely held in the earth.

It will be noted that by providing the' cross head, 8, with a threadedaperture to receive the operating rod that the necesslty A of providingoperatingnuts or other devices is entirely obviated.

From the foregoing description, taken in connection with theaccompanying drawings, the construction .and operation of the inven`tion will be readil)1 understood without re- I quiring a more extendedexplanation.

Varlous changes in the form, proportion 'and Vthe minor details ofeonstrnctimi may. -be resorted to without departing' Troni the.lprinciple or sacrltiemg any ot the invention as defined in the appendedclaim.

lhat I claim, and desire to secure by Letters-Patent is:

In a postbrace anchor, an expander comprising a edge-shaped,frame having.a substantially circular base, an operatingrod havingja swivelengagement with said ex-v pander, a cross head having a screw-threadj edengagement with said rod, bearlngs -formed onLthe' outer ends of saidcross head,

wings in an inoperative position, said lmeans being adapted to be brokenby the expansion of the wings.' "f

ln testimony whereof I have hereunto set my hand' in presence'of thesubscribin'gwitnesses.
